           Summary: KWrite crashes on code folding
           Product: kate
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: kwrite
        AssignedTo: kwrite-devel kde org
        ReportedBy: akarshsimha gmail com


Version:           3.97.1 (using KDE Devel)
Installed from:    Compiled sources
Compiler:          g++ 4.2.3 

On opening a diff with KWrite, it was highlighted correctly. However, it showed code-folding options \
which is not expected in a diff. On trying to fold the second nested level, KStars crashed.

The Backtrace is pasted below:
